TORONTO, Ont. – TTC CEO Andy Byford apologized publicly for Monday’s evening rush hour commute that was plagued with delays.

Byford explained the delays in a YouTube video Tuesday.

The delays were caused by several reports of smoke at track level, a door opening while the train was in a tunnel near Dupont station and number of passenger assistance alarms, including one following an assault. Toronto police confirmed to 680News that three people were arrested at Bloor-Yonge station in connection to the assault.

The incident at Dupont caused a 24-minute delay.

“Just as evening peak was building we had two fire alerts — one at Eglinton, one at Keele station. In such circumstances, we put safety first. We don’t take any risks,” Byford said in the video.

Byford also discussed the TTC’s first-ever customer charter.

“Key to that improvement is increased reliability and punctuality of the service and clearly, we didn’t meet that objective last night so once again I am sorry for the delays last night,” he said.

“I appreciate it was a frustrating trip home.”

TTC Chair Karen Stintz told CityNews that it was a series of issues occurring simultaneously and admitted mistakes were made in the management of the issues.

“Events happen. We need to manage them better. We need to communicate more effectively and so we’ve taken a lot of lessons from this experience and how we can better manage these kinds of events,” she said.

A number of social media users wondered if Byford used a green screen for his video.

TTC spokesperson Brad Ross said it was filmed at Bloor-Yonge station on the northbound platform.

On Monday night, many frustrated TTC riders took to social media to vent their frustrations.
